joining friend games

I saw so many "clans" in CubeCraft and they should be reconized by the nickname that players change everytime, for exemple BloodFor clan members nicknames are "BloodFor(nickname)" I hope you get what I mean. It's kinda annoying that to join a clan you need to change nickname and you can do it...

Does this happen to anyone else?You log onto CubeCraft and your friend is in a game and you ask how much left and they reply with a while.-_-It really annoys me and if you join a game while there playing that game might go on after their game is over.So I really think there should be an option...
